Abstract
A display device and a method for remotely controlling the display device are disclosed. A controller executes a first application and a second application. A display displays a main window, which displays an execution screen of the executed first application, and a first sub window which displays an execution screen of the executed second application, on a screen. A receiver receives a focus switching signal from a first remote controller and a coupling signal containing an identifier from a second remote controller. The controller switches a focused window based on the received focus switching signal and implements coupling between the focused window and the second remote controller in response to the received coupling signal.
Claims19
A method for remotely controlling a display device, the method comprising:
- displaying a main window, which displays an execution screen of a first application, on a screen of the display device;
- executing a second application and displaying a first sub window, which displays an execution screen of the executed second application, on the screen;
- receiving a signal for changing a focus from a first remote controller, the first remote controller being coupled with the main window;
- switching a focused window based on the received signal;
- receiving a coupling signal containing an identifier from a second remote controller;
- coupling the focused window with the second remote controller in response to the received coupling signal;
- displaying a coupling execution checking message by means of the second remote controller;
- receiving an approval signal from the first remote controller in response to the message;
- and
- displaying a coupling execution guide message in response to the received approval signal.
A display device comprising:
- a controller to execute a first application and a second application;
- a display to display a main window, which displays an execution screen of the executed first application, and a first sub window which displays an execution screen of the executed second application, on a screen;
- and
- a receiver to receive a signal for changing a focus from a first remote controller and to receive a coupling signal containing an identifier from a second remote controller,
- wherein the controller controls to change a focused window based on the received signal and implement coupling between the focused window and the second remote controller in response to the received coupling signal, and
- wherein the controller controls display of a coupling execution checking message by means of the second remote controller, and controls display of a coupling execution guide message if an approval signal from the first remote controller is received in response to the coupling execution checking message.
A method for remotely controlling a broadcast receiver, the method comprising:
- receiving a broadcast signal;
- demodulating the received broadcast signal;
- decoding the demodulated broadcast signal;
- outputting the decoded broadcast signal through a first window on a screen, wherein the first window is coupled with a first remote controller;
- outputting an execution screen of an application through a second window on the screen;
- receiving a first signal for requesting a coupling from a second remote controller;
- outputting a first message for initializing a coupling execution between the second window and the second remote controller;
- receiving an approval signal from the second remote controller in response to the first message;
- outputting a second message for guiding the coupling execution in response to the received approval signal;
- receiving a coupling signal from the second remote controller;
- and
- coupling the second window with the second remote controller in response to the received coupling signal.
